Meniscotibial (coronary) ligament tears

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Anatomy

Background:

• Meniscal preservation is crucial for knee joint stability.
• Preventing premature osteoarthritis is a primary goal in knee surgery.
• Peripheral meniscal tears are often repairable, making them targets for surgical intervention.

Purpose of the Study:

• To evaluate the peripheral attachments of the medial meniscus.
• To focus on tears specifically involving the meniscotibial ligament (coronary ligament).
• To describe the arthrographic diagnostic criteria for this specific meniscal injury.

Main Methods:

• Review of peripheral medial meniscus attachments.
• Analysis of tears localized to the meniscotibial ligament.
• Description of arthrographic findings: medial meniscus floating above the tibial plateau.

Main Results:

• The meniscotibial ligament (coronary ligament) is a key attachment of the medial meniscus.
• A specific arthrographic sign involves the medial meniscus floating without complete capsular separation.
• This type of injury predominantly affects the medial meniscus, with rare lateral meniscus involvement.

Conclusions:

• Understanding the meniscotibial ligament's role is vital for meniscal repair.
• Arthrography provides a diagnostic method for identifying these specific peripheral meniscal tears.
• Successful meniscal preservation strategies are essential for long-term knee health.
